68 Firebird Ram Air II stuff

If any of you guys know where I can find the following (factory original) please tell me (and not anybody else :D ) I am looking for an original Pontiac 400 motor with a late 68 date code and 96 coded heads (I am talking about the L67 motor). Now attached to this motor, I also want the original TH400 auto-tranny and the original 68 Firebird Convertable that came with it as well.;) Cost really isn't an issue (well ok maybe a little issue).....

Thanks fer all the help :D
